Judge Blocks NCAA Bid to Stop DraftKings’ March Madness Trademarks
A federal judge rejected the NCAA’s request for a preliminary injunction against DraftKings on March 2025, allowing the daily fantasy sports and sports betting giant to keep running promotions that use the phrase “March Madness” and associated branding. The NCAA, which holds registered trademarks on “March Madness” and “The Big Dance,” argued that DraftKings’ use of those marks created consumer confusion and diluted the organization’s brand. The court’s decision is a significant early win for DraftKings and sets a precedent that could reshape how sports betting operators market around major sporting events.
Federal Judge Denies NCAA’s Emergency Motion to Block DraftKings’ Trademark Use
What the Court Actually Decided
The NCAA filed for a preliminary injunction seeking to immediately halt DraftKings from deploying “March Madness” branding across its betting platform, mobile app, and advertising materials during the 2025 NCAA Tournament. U.S. District Judge denied that request, finding that the NCAA failed to demonstrate the likelihood of irreparable harm required to justify emergency injunctive relief. The ruling does not resolve the underlying trademark lawsuit, which will continue through the normal litigation process.
To obtain a preliminary injunction, a plaintiff must satisfy a four-part legal test: likelihood of success on the merits, likelihood of irreparable harm without the injunction, that the balance of equities tips in the plaintiff’s favor, and that the injunction serves the public interest. The court found the NCAA fell short on at least the irreparable harm prong, a critical threshold that stopped the emergency relief in its tracks. This is a procedural victory for DraftKings, not a final ruling on whether the company has the right to use those trademarks permanently.
Legal analysts following the case note that courts apply a high bar for emergency injunctions precisely because they impose immediate restrictions before a full trial on the merits. The NCAA’s failure to clear that bar means DraftKings can operate its March 2025 tournament promotions without restriction while the case moves forward [1].
The NCAA’s Trademark Claims Explained
The NCAA has held federal trademark registrations for “March Madness” since the 1990s, and the phrase has become one of the most commercially valuable sports trademarks in the United States. The organization licenses the mark to official sponsors including AT&T, Capital One, and Coca-Cola, generating tens of millions of dollars in annual licensing revenue. The NCAA argued that DraftKings’ use of the phrase in betting promotions implied an official sponsorship relationship that does not exist.
DraftKings countered that “March Madness” has entered common usage as a descriptive term for the NCAA Tournament and that its use constitutes nominative fair use, a legal doctrine that allows a party to reference a trademarked term when describing the actual product or event. The company also argued that consumers clearly understand DraftKings is not an official NCAA partner. The fair use argument, if it succeeds at trial, could open the door for other sports betting operators to use tournament branding without licensing fees.
What This Ruling Means for DraftKings, the NCAA, and the Sports Betting Industry
DraftKings Gains a Critical Marketing Window
The NCAA Tournament generates more legal sports betting handle in the United States than almost any other event outside the Super Bowl. According to the American Gaming Association, Americans wagered an estimated $2.7 billion legally on March Madness in 2024, a figure that has grown every year since the Supreme Court struck down the federal sports betting ban in Murphy v. NCAA in May 2018 [2]. Losing the ability to use “March Madness” in marketing during the tournament itself would have cost DraftKings a measurable share of that market.
DraftKings is one of the two dominant operators in the U.S. legal sports betting market alongside FanDuel, and the two companies together account for roughly 70% of online sports betting market share nationally. Tournament season is peak customer acquisition time, and brand visibility during March directly influences new user registrations and deposit volumes. The court’s denial of the injunction preserves DraftKings’ ability to compete on equal footing with FanDuel and other rivals who may use similar descriptive language.
Long-Term Implications for Sports Betting Marketing
If DraftKings ultimately prevails on the fair use argument at trial, the ruling could establish that sports betting operators have broad latitude to reference event names in promotional materials without paying licensing fees to governing bodies. That outcome would represent a structural shift in the economics of sports betting marketing, reducing one potential cost center for operators. Conversely, an NCAA victory at trial would force the entire industry to negotiate licenses or avoid using iconic event names entirely.
The NCAA’s relationship with legal sports betting is already complicated. The organization spent years opposing sports betting legalization, then gradually softened its stance as state-by-state legalization became a reality after 2018. As of 2025, legal sports betting is live in 38 states plus Washington D.C., and the NCAA has begun exploring official data partnerships and limited sponsorship arrangements with betting operators [1]. This lawsuit signals the organization is still drawing firm lines around its core intellectual property even as it warms to the industry.
The $2.7 Billion March Madness Betting Market in 2025
| Year | Estimated Legal Handle | States with Legal Betting |
|---|---|---|
| 2019 | ~$400 million | 8 |
| 2021 | ~$1.2 billion | 21 |
| 2023 | ~$2.3 billion | 33 |
| 2024 | ~$2.7 billion | 38 + D.C. |
The March Madness betting market has grown more than sixfold since sports betting was federally legalized in 2018, driven by rapid state-by-state adoption and aggressive marketing by operators like DraftKings, FanDuel, BetMGM, and Caesars Sportsbook. The American Gaming Association reported that 68 million Americans planned to fill out brackets in 2024, and a substantial portion of those participants also placed legal wagers [2]. That audience size makes tournament branding extraordinarily valuable to any operator competing for market share.
DraftKings reported $3.67 billion in total revenue for fiscal year 2024, a 43% increase year-over-year, with March representing one of its highest-volume months [3]. The company’s ability to market directly using the “March Madness” name, rather than circumlocutions like “the big college basketball tournament,” carries real conversion value in digital advertising where character counts and brand recognition drive click-through rates. Restricting that language mid-campaign would have disrupted paid search, social media, and email marketing strategies already in flight.
The broader context here is that sports governing bodies are increasingly protective of their intellectual property as betting revenues grow. The NFL, NBA, MLB, and NHL have all secured official data and marketing partnerships with sportsbooks, creating revenue streams tied directly to betting activity. The NCAA, which governs amateur athletics and has historically been more restrictive, is navigating a different set of institutional pressures as it balances amateurism principles against commercial realities.
Why Crypto and Blockchain Finance Readers Should Watch This Case
The DraftKings-NCAA trademark dispute has a direct parallel in the blockchain space: the question of who controls branded intellectual property when decentralized or semi-decentralized platforms use established names to attract users. Several blockchain-based prediction markets and decentralized sports betting protocols, including Augur and Polymarket, have faced similar questions about whether referencing real-world event names in smart contract markets constitutes trademark infringement or fair use. The legal framework being tested in the DraftKings case will inform how those disputes are eventually adjudicated.
Crypto-native sports betting platforms are growing rapidly. Blockchain-based sportsbooks processed an estimated $3 billion in wagers globally in 2024, according to industry tracking data, and many of these platforms operate outside U.S. jurisdiction while serving American users. A ruling that broadly protects fair use of sports event names would benefit these platforms by reducing legal exposure if they ever seek U.S. regulatory compliance. A ruling favoring the NCAA would add trademark licensing costs to the already complex regulatory burden facing crypto betting operators seeking legitimacy in regulated markets.

Frequently Asked Questions
Can DraftKings legally use the term March Madness in its ads?
As of the court’s March 2025 ruling, yes. The judge denied the NCAA’s emergency injunction, so DraftKings can use the term during the 2025 tournament. Whether that right extends permanently depends on the outcome of the underlying trademark lawsuit, which is still pending. DraftKings argues nominative fair use protects its ability to reference the tournament by name.
Does the NCAA own the trademark for March Madness?
Yes. The NCAA holds federally registered trademarks for “March Madness” and “The Big Dance” and has enforced those marks commercially since the 1990s. The organization licenses the trademarks to official sponsors and generates tens of millions of dollars annually from those agreements. The current lawsuit tests the limits of that trademark protection against fair use claims [1].
What is nominative fair use in trademark law?
Nominative fair use is a legal doctrine that permits a party to use another’s trademark when referring to the actual trademarked product or event, provided the use does not imply sponsorship or endorsement. Courts typically require that the product cannot be identified without using the mark, that only so much of the mark is used as necessary, and that nothing falsely suggests sponsorship. DraftKings is relying on this doctrine to defend its March Madness promotions.
How much do Americans bet on March Madness each year?
The American Gaming Association estimated that Americans placed approximately $2.7 billion in legal sports wagers on the 2024 NCAA Tournament, up from roughly $400 million in 2019 when legal betting was available in only 8 states [2]. The figure has grown every year alongside expanding state-level legalization, and 2025 projections are expected to meet or exceed the 2024 total.
The Bottom Line
The federal court’s denial of the NCAA’s injunction request is more than a procedural footnote. It signals that courts are willing to give sports betting operators room to operate during live events while complex intellectual property questions get resolved through full litigation. For DraftKings, the ruling preserves millions of dollars in marketing effectiveness during the single most important betting month of the college sports calendar.
The NCAA faces a harder strategic question. Its long-standing resistance to sports betting is giving way to pragmatic commercial engagement, yet this lawsuit shows the organization still intends to monetize its brand assets aggressively. How the underlying case resolves will define the rules of engagement between sports governing bodies and betting operators for years to come, affecting licensing economics, marketing strategy, and potentially the cost structures of blockchain-based sports betting platforms seeking U.S. market access.
The outcome of this case will not just affect two parties in a courtroom. It will set the terms on which a $10 billion-plus U.S. sports betting industry communicates with its customers every March.
